The IOP courses in 159 eyes with primary angle closure glaucoma (PACG) under continuous medical therapy alone were observed. The follow-up period was 5 to 33 years, with an average period of 12.4 .+-. 6.2 years. Six (43%) out of 14 eyes with acute PACG under medical therapy had re-attacks while one eye (7%) developed increased IOP. In 47 fellow eyes of acute PACG, which were under prophylactic local medication only, 12 eyes (26%) developed acute attacks while 3 eyes (6%) developed increased IOP. Of the 98 eyes with chronic PACG under medical therapy, 7 eyes (7%) developed acute attacks and 46 eyes (46%) developed increased IOP. Eventually, about half of the eyes with PACG, which were under continuously local medication, developed uncontrollable IOP. This study suggests that long-term medical therapy for PACG is not satisfactory.
